Yes, it's possible you're pregnant. A woman can get pregnant at just about any time during the month, although the most fertile time is usually about day 14 (if you're on a 28 day cycle). It would all depend on when you ovulated. I know women who have had their periods throughout their entire pregnancy or for just a few months. Usually, it's irregular and light, but sometimes it's full b__wn. I would suggest taking a hpt in a few days and see what happens. Whether or not it comes back positive, I would then suggest waiting a week and taking another one. Good luck.

Let's get this right! You thought your period was coming the 7th, so when it didn't come you thought, let's make hay until it gets here, all through the 8th, 9th and 10th. On the 11th there came a short period. S_x on the weekend is too recent for the short period to be implantation. If it was implantation it would be from s_x in the first several days of the month. Also if it was implantation you would now be complaining about at least a few early pregnancy symptoms, which I do not hear. In my opinion, the chances of you being pregnant are slim. Please double up on contraception (foam+condom) until your cycle gets back to normal. Good luck!
